  • Objectives : The purpose of this study is to examine the efficacy of fire needling and warm needling for De Quervain Syndrome by reviewing clinical studies for recent 10 years. Methods : Randomized controlled trials, non-randomized controlled trials, and case series containing more than 20 cases about fire needling and warm needling for De Quervain Syndrome published since 2011 were searched through four foreign online databases (CNKI, Pubmed, EMBASE, Cochrane Library) and five Korean online databases (OASIS, Science ON, DBPIA, KISS, RISS). The number and characteristics of participants, treatment points and main treatment methods involving other combination treatments, treatment cycle or total periods of treatments, evaluation indices, efficacy, and adverse events were analyzed. Risk of bias of included randomized clinical trials was assessed using a revised tool for assessing risk of bias in randomized trials (RoB 2). Results : A total of 6 randomized clinical trials and 2 case series involving 471 participants were included. Tender point or 'Ashi point' was the most commonly used treatment point, followed by LU4. Treatment frequency ranged from once a day to once a week. One to three outcome measures were used to evaluate the results of the studies, with the efficacy rate the most frequently used, followed by visual analogue scale. Overall risk of bias of all included randomized clinical trials was judged to have some concerns. Conclusions : All selected studies showed that fire needling and warm needling treatments for De Quervain syndrome were more effective than other clinical methods or acupuncture treatments. However, as the number of clinical studies is still too small and the risk of bias of the studies is not low, it is believed that more systematic and objective studies should be conducted.

  • The purpose of this study was to investigate the supply and demand structure of the domestic space industry through analysis of industrial concentration index, by sector and dependence on revenue by customer type. As a result of industrial concentration analysis, in the case of space application, a supply monopoly or oligopoly structure was revealed in fields such as satellite broadcasting, space insurance, and satellite navigation. In the field of space equipment manufacturing, referred to as the traditional space industry, a supply monopoly structure appeared only in the field of launch pads and test facilities. As a result of analyzing the dependence on revenue by customer type, the dependence on the demand in the space application field is diversified among foreign countries, private institutions, and others. However, in the case of space equipment manufacturing, it is highly dependent on the demand of public institutions, and it seems that there is a monopsony structure.

  • The purpose of this study is to propose the direction of convergence design curriculum of domestic universities in order to cultivate ablility of empathy in the $4^{th}$ industrial revolution era. The research methodology was firstly reviewed through the literature review, and the theoretical background about the background and design reengineering which became important in the time of the superconducting connection was examined, and the case study of the present situation of the convergence design curriculum of the domestic and foreign universities. As a result, it suggests a curriculum for the integration of undergraduate and graduate curriculum, which is a curriculum in which the design based on empathy is the key to linking other academic fields. Based on this, I hope that it will be used as a reference material for the activation of convergence design education in Korea in the future.

  • In Korea, more than 70% of the ammonia(NH3) released into the atmosphere is known to originate from livestock manure. The total emission (kg year-1) is calculated by multiplying the emission factor (kg head-1 yr-1) and the activity data (head). To improve the accuracy and reliability of the NH3 emission estimation process, an accurate account of livestock manure production, calculation of NH3 conversion and generation during the composting and liquefaction of manure, estimation of NH3 generation in the storage and transportation of manure and compost, and a comparative study of NH3 emission during the soil spreading process must be performed. Compared to the US and EU-28, in particular, the domestic emission factor is relatively even and the spatial/temporal scale is not broken down sufficiently to reflect the domestic situation. As a way to improve the accuracy and expertise of estimating NH3 emission factors, a 'dynamic chamber-capture system' can be utilized, which allows complex considerations of compost, liquid manure, soil, and climate characteristics. By reviewing and comparing the data related to domestic and foreign NH3 emission, we identified shortcomings in the current domestic system and the directions to be taken and suggested a chamber system that could estimate NH3 emission flux. It is also necessary to establish a methodology for mesocosm systems in the field, in addition to indoor chamber systems, to be linked with practical policies, such as the calculation of new emission factors for missing sources.

  • Recently, media diplomacy takes on a substantial role in information war not only in setting global agenda but also in delivering their favored views and frames. Focusing on its crucial impact, this study attempts to investigate empirically the relationship between national prestigious media's news coverage and it's own foreign policy particularly about the 2011 Libya conflict. The total of 530 news articles in such 24 hour English news channels as BBC World, Cnn International, Russia Today, France24, Al Jazeera English and Deusche Welle were analyzed for this study. The analyses reveal that Libya coverages of those news channels are entirely constructed in the context of the foreign policy. To put it concretely, there was the undeniable level of differences in terms of quoting relevant sources, viewpoints, attitudes and frames for the pursuit of media diplomacy helped by high quality journalism. The authors argue in this regard that protecting information sovereignty should be urgently discussed even in the time of digital revolution. To launch 24-hour English news channel like 'Korea 24' would be a possible strategy for influencing global agenda and perspective in way of supporting national interests.

  • Korea has recently selected twenty-two ports for reinforcement breakwater installation of protection facilities, due to rise sea level caused by global warming and increase in the number of typhoon and tsunami. In addition, due to consistent enlargement of ship size, dredging for depth of water for large vessel's berthing and enlargement of berth is under construction. However, no definite construction plan for the reinforcement and lengthening of crown height, which has close relationship with the safe mooring of ships. In this study, domestic and foreign design criteria of crown height were analyzed, and the crown height evaluation index and evaluation method were developed by dividing it into environment and ship elements. In particular, in the case of ship evaluation index, each step was set up in 4 steps according to domestic and foreign regulations, weighted by each step, and the safety level of crown height was evaluated. As a result of the mooring safety simulation of the 100,000 ton cruise ship, the appropriate minimum crown height standard was derived to be 3 m above A.H.H.W. The results of this study are expected to be used as basic data to propose the crown height standard reflecting ship characteristics.

  • Purpose - This study aims to analyze the characteristics of network construction by Norwegian Air and AirAsia X, which are recognized as leading airlines in the long-haul LCC market. Based on this analysis, this study intends to provide implications for networking strategies for Korean LCCs that seek to enter the long-haul market when the aviation market stabilizes again upon the end of the COVID-19 pandemic. Design/methodology - To conduct the network analysis on long-haul low-cost airlines, the Official Airline Guide (OAG) Schedule Analyzer was used to extract long-haul data of Norwegian Air and AirAsia X. To analyze the trend of the long-haul route network, we obtained the data from 3 separate years between 2011 and 2019. The network was analyzed using UCINET 6.0 in order to examine the network structure of long-haul low-cost airlines and the growth trend of each stage. Findings - Analyzing the network of long-haul routes by visualizing the network structure of low-cost carriers showed the following results. In its early years, Norwegian Air's long-haul route network, centering on regional airports in Spain and Sweden, connected European regions, the Middle East, and Africa. As time passed, however, the network expanded and became steadily strong as the airline connected airports in other European countries to North America and Asia. In addition, in 2011, AirAsia X showed links to parts of Europe, such as London and Paris, the Middle East and India, and Australia and Northeast Asia, centering on the Kuala Lumpur Airport. Although the routes in Europe were suspended, the network continued to expand while concentrating on routes of less than approximately 7,000 km. It was found that instead of giving up on ultra-long-haul routes such as Europe, the network was further expanded in Northeast Asia, such as the routes in Korea and Japan centering on China. Originality/value - Until the COVID-19 pandemic broke out, Norwegian Air actively expanded long-haul routes, resulting in the number of long-haul routes quintupling since 2011. The unfortunate circumstance, wherein the world aviation market was rendered stagnant due to the outbreak of COVID-19, hit Norwegian Air harder than any other low-cost carriers. However, in the case of AirAsia X, it was found that it did not suffer as much damage as Norwegian Air because it initially withdrew from unprofitable routes over 7,000 km and grew by gradually increasing profitable destinations over shorter distances. When the COVID-19 pandemic ends and the aviation market stabilizes, low-cost carriers around the world, including Korea, that enter the long-haul route market will need to employ strategies to analyze the marketability of potential routes and to launch the routes that yield the highest profits without being bound by distance. For stable growth, it is necessary to take a conservative stance; first, by reviewing the business feasibility of the operating a small number of highly profitable routes, and second, by gradually expanding these routes.

  • The purpose of this study was to examine what kind of images were presented on movie stars in the newspaper. For the purpose, we classified the time period according to the movie industry and media trend, selected representative stars by period, and collected 798 related articles reported in newspapers. As a result of analyzing the reporting trend, domestic and foreign topics, news format, and gender difference in collected movie star articles, it was found that the image of movie stars reproduced in newspaper articles had mostly neutral images that do not represent specific gender. Since the 2000s, news coverage was changed to reproduce various images rather than being fixed to particular images, and the subject of report became more diversified through comparison of domestic and foreign topics. In addition, articles in the form of book review decreased and the interview-type articles increased in number, and in the case of male movie stars, the proportion of articles based on works was high in comparison to female movie stars. This study has significance in that it explored the changes in the process of reproducing star images diachronically from the initial stage of stars to the modern times. And it is hoped that this study will serve as basic data for the follow-up studies on the process of reproducing various images in the multi-media era.

Fashion Design Study on Korean Traditional Image Suitable for Ramie Fabric(I) - The Application of Aesthetic Property of Goguryeo Era Clothing - (모시 소재에 적합한 한국적 이미지의 의상디자인 개발에 대한 연구(제1보) - 고구려 시대 복식의 미적 특징을 적용하여 -)

  • A recent concern about Goguryeo era reflects the efforts to find out our spiritual roots, which have descended from the ancient times; Goguryeo clothing study leads to analysis of our national spirit in terms of form. This study aims to analyze formal property and intrinsic meaning of Goguryeo clothing for Korean ramie clothing design and draw traditional images to derive design elements applicable to ramie clothing. On the basis of technical books, newspaper article, internet and precedent studies, theoretical study on Goguryeo clothing and ramie property was followed up with positive study to analyze the clothing on the Goguryeo ancient tomb mural. The results are as follows: First, a progressive spirit is to progress and develop anything actively; This spirit represents Goguryeo people's ambition and racial characteristic as horse-riding people; The rigidity of ramie fabric is suitable for expressing straight silhouettes and detail in Goguryeo dress. Second, a fluidity means flowing property in opposition to fixation; in the case of clothing, it has a tendency to change form according to body motions; The extensibility and crease-resistance of ramie fabric is suitable to express pleated skirts and holds high design value for modern people who tend to regard clothing as important individuality expression. Third, a universal property to introduce and receive; as Goguryeo was a prosperous country established by conquering an open plain, the period formed a society that recognized diversity by introducing foreign cultures freely; a universality suggests the direction of modernization of traditional ramie clothing and stimulates us to discovert new design through compromise between various cultures rather than to stick to traditional style. Considering the fact that precedent studies on traditional clothing are concentrated upon the Joseon period and also limited to formal analysis, this study aims to derive design elements for actual clothing making. These results are expected to be used as basic material for study as well as reference for designers who wish to design modern Korean clothing.
